Description

[Detailed description of the invention] The present invention relates to a food ticket vending machine.

Normally, a food ticket vending machine is provided with a money slot, a money receiving slot, and a push button on the customer service side, and when money is inserted and a designated push button is pressed, a ticket for the specified dish will be sold by that push button.

In this case, meal tickets are simply sold, regardless of how many servings of cooking ingredients are purchased that day.

Conventionally, when an ingredient runs out in the kitchen, a sold-out display board is hung on the button on the customer service side of the vending machine where the ingredient runs out, or a switch is turned to display a sold-out display, indicating that the dish is sold out. it's shown.

For this reason, each time an ingredient runs out, it is necessary to hook a sold-out display board to the push button that sells the meal ticket for the dish for which the ingredient is no longer available, or to operate a changeover switch, which is not only troublesome, but also prevents the ticket from being sold. Since it is not known how many servings of unmade dishes are available, it is necessary to display the sold-out status earlier than the number of dishes that can actually be sold, which makes timing difficult.

Later, mechanical or electromagnetic order quantity setting devices appeared, but these devices are large and complicated and are not actually used.

Therefore, the present invention employs a unique electronic method to automatically prevent the sale of meal tickets once the number of meal tickets for the purchased raw materials has been sold.

The present invention will be explained below with reference to embodiments shown in the drawings.

Reference numeral 1 denotes a control circuit for a food ticket vending machine, and since this is well known, detailed explanation will be omitted.

2 is a cumulative counter that counts the number of food tickets sold for each type of dish, and 3 is a preset counter that has a counter for each type of dish.This counter 3 shows the number of dishes that can be made with the raw materials purchased that day for each type of dish. A number setting device 4 is connected.

When a meal ticket is sold in a vending machine, a signal is manually sent from a control circuit 1 to a preset counter 3, and one ticket is subtracted from the number of tickets set in the counter corresponding to the ticket in a number setting device 4.

When the number of food tickets continues to be sold and reaches the number set in the number setting device 4, the preset counter 3 sends a sales stop command signal to the control circuit 1, disabling the sale of the food ticket, displaying that the food ticket is sold out, and notifying the customer that the food ticket is sold out. Inform.

5 is a display that displays the number of dishes to be cooked for each type of dish, and is installed in the cooking area.

When the food is prepared and handed to the customer, the number of dishes served is subtracted and displayed based on the operation of the reset device 6.

Furthermore, when a sales stop command signal is output from the preset counter 3, the display 5 displays it to notify the cook that the dish is sold out.

The above control circuit 1 and preset counter 3 are installed in the vending machine, and the display 5 is installed in the kitchen, but the cumulative counter 2 and the number setting device 4 can be installed in the vending machine or in the kitchen. You can.

The above-mentioned main parts will be explained in more detail based on FIG.

Although the drawing shows only one digit for one dish, in reality, several digits are required for one dish for multiple types of dishes.

In the figure, the sales quantity is set by a digital switch 17 consisting of 4 bits (B3 to BQ).

7...and gate, 8 is 4 bits B3~Bo
9 is a selection switch that opens and closes when a push button is pressed, 10 is an AND circuit, and 11 is a flip-flop.

The signal representing the sales quantity set in the digital switch 17 is sent to the preset counter 8 as a signal 12 which is emitted when the vending machine starts selling, and then as a preset signal 13. It is stored in the preset counter 8 and inputted to the AND circuit 10 from there.

In this state, when money is inserted into the vending machine and any push button within the amount of money is operated, the selection switch 9 of that push button is closed, the AND circuit 10 is opened, and the flip-flop 11 is set. and sends out a sales signal 14.

The vending machine sells food tickets corresponding to the push button in response to this sales signal 14, inputs the down signal 15 to the preset counter 8, subtracts it from the preset counter 8, and sends the subtracted signal to the preset counter. 8 to the AND circuit 10.

After selling the food ticket, the flip-flop 11 is reset to a sales preparation state.

Thereafter, the above operations are repeated each time money is inserted and the push button is pressed to sell a meal ticket.

When the content stored in the preset counter 8 becomes zero, the signal from the preset counter 8 becomes an involuntary signal, and even if the selection switch is closed, the AND circuit 10 remains closed and no longer outputs the sales signal 14. , cannot sell food tickets related to this circuit.

Also, based on the signal from the preset counter 8,
The sold-out lamp 16 is turned on and the push button lamp is not turned on.

In addition, as a measure against power outages, it is recommended to incorporate a battery into the power supply or use a preset counter that can handle such power outages.

Furthermore, the meal ticket may be made of paper, plastic, or any other material.

As is clear from the above explanation, according to the present invention, the purchase amount of ingredients for a dish is set, and when the number of meal tickets sold reaches the set number, the meal tickets are automatically stopped from being sold.
This will lead to rationalization of the cafeteria.

Claims (1)

[Claims] 1. The customer service side has a money slot, a meal ticket receiving slot, and a push button for each ticket, so that when money is inserted through the money slot and a push button is operated, the food ticket corresponding to that push button is sold. In vending machines, 4 bits (B3~BO
) and the sales start signal 12 by the AND circuit 7 and the preset signal 13 to preset the preset counter 8, and
The outputs of o are combined into one, and this output and the output of the selection switch 9 are ANDed by the AND circuit 10 to set the flip-flop circuit 11, and the output is set as the sales signal 14.
This food ticket vending machine is characterized in that a preset counter 8 is subtracted by a down signal 15 generated by sales, and a flip-flop 11 is reset by a reset signal generated in the same manner.
